Objectives : The anticancer response of three different types of water extracts of Zingiberaceae Curcuma longa L. tested for sarcoma 180. Only few studies carried out to investigate the effects of other contents of Curcuma longa L. in anticancer activities, therefore, in this study we have investigated the effects of other component then curcumin in Curcuma longa L. for anticancer a activities. Methods : Three different types of water extracts of Curcuma longa L. were prepared as follows. The sarcoma cells (S180) were maintained in Dulbecco's modified Eagle's medium (DMEM) and were seeded on 24-well cell culture cluster flat bottom with lid tissue culture treated non-pyrogenic polystyrene. The growth of sarcoma 180 was monitored for 1, 2 and 5 days. The sarcoma cells were pictured using inverted microscope and cell density was counted using hemocytometry. Results : After 5 days in the culture medium the results showed high growth of sarcoma 180 for control condition and the surface of CCP plates were fully covered with the cells. In case of medium in which the 10% of filtered water extract of Curcuma longa L. was added a very limited growth of sarcoma 180 was observed. The results were showed only small difference in cell density for two different concentrations of unfiltered water extracts of Curcuma longa L. whereasin case of filtered water extracts the control of sarcoma growth shows better result. Conclusion : The filtered water extracts showed the best result relatively to the unfiltered water extracts for two different concentrations. This indicates that the water extracts of Curcuma longa L. can have anticancer activities possibly without curcumin.

The objectives of the present study were to select an effective basic medium including its hormone and protein supplementation for IVM of oocytes of indigenous zebu cows. The ovaries of cows were collected from slaughter house and the follicular fluid was aspirated from 2 to 8 mm diameter follicles. The COCs with more than 3 cumulus cell layers and homogenous cytoplasm were selected for maturation. The oocytes were matured in media for 24 hrs at $39^{\circ}C$ with 5% $CO_2$ in humidified air. The maturation of oocytes was evaluated by examining the presence of first polar body under microscope. An efficient basic medium was determined after culturing COCs in either TCM 199 or SOF medium in Experiment 1. An efficient hormone supplementation was determined after culturing COCs in either FSH or gonadotrophin supplemented TCM 199 in Experiment 2. An efficient protein supplementation was determined after culturing COCs in either FBS or Oestrous cow serum (OCS) supplemented TCM 199 in Experiment 3. The oocyte recovery rate per ovary was 3.35. The overall rate of IVM was 74.6%. The maturation rate was $75.5{\pm}3.9$ and $62.2{\pm}20.2%$ in TCM and SOF medium, respectively (P>0.05). The maturation rate of oocytes was significantly higher ($76.6{\pm}13.2%$) in FSH supplemented medium than gonadotrphin supplemented counterpart ($69.7{\pm}10.8%$) (P<0.05). The maturation rates of oocytes were $81.7{\pm}12.9$ and $85.7{\pm}12.7%$ in medium supplemented with FBS and OCS, respectively (P>0.05). In conclusions, both TCM 199 and SOF supplemented with either FBS or OCS, and FSH may be used as medium for IVM of indigenous zebu oocytes in Bangladesh.

Objectives : Quality control of the needle tips and prevention of pollutions are important factor for safe and effective acupuncture treatment. Ear acupuncture needle is made by 3 companies in Korea, and used to treat for obesity or smoking in clinic frequently, but the Korean industrial Standard is proposed most recently. In spite of the importance, there has been little study about that. Moreover, there was no study about ear acupuncture needle. Methods : We investigated the current condition of needle shape and pollution about the tips and body of the ear acupuncture needle under the stereoscopic microscope. Samples are selected 100 pieces from 300 pieces randomly in each company. Results : The substandard needles are classified into four groups and counted 1. Normal condition (55.3%), 2. Scratch on the surface (14.0%), 3. Malformation of tips (19.3%), 4. Pollution of body (4.3%), 5. Multiple Substandard (7.0%). In the case of including type 2 as a standard needle, normal rate of A company was 81% when B was 76%, and C was 51%. Conclusion : The substandard ear acupuncture needles can induce local side effects such as needling pain or itching. Furthermore, it can disturb the proper effect of acupuncture treatment. We hope that this study can help to improvequality of ear acupuncture and reduce substandard rate for safe and effective ear acupuncture treatment.

Objectives : Alzheimer's disease (AD) is a geriatric dementia that is widespread in old age. In the near future AD will be the biggest problem in public health service. Although a variety of oriental prescriptions, including Sesim-tang, have been traditionally utilized for the treatment of AD, their pharmacological effects and action mechanisms have not yet been fully elucidated. The present study investigated the effects of Sesim-tang on apoptotic cell death induced by CT105 (carboxy terminal 105 amino acid peptide fragment of APP) overexpression in SK-N-SH neuroblastoma cell lines. Methods: We studied the regenerative and inhibitory effects on Alzheimer's disease in CT105-induced SK-N-SH cell lines by Sesim-tang water extract. We examined for cell morphological pattern, DNA fragmentation, LDH activity assay, zymography assay, and immunohistochemistric analysis. Additionally, we investigated the association between the CT105 and neurite degeneration caused by CT105-induced apoptotic response in neurone cells. Results: Findings from our experiments have shown that Sesim-tang inhibits the synthesis or activities of CT105, which has neurotoxicities and apoptotic activities in the cell line. In addition, pretreatment with Sesim-tang ($>50\mu\textrm{g}/ml$ for 12 hours) partially prevented CT105-induced cytotoxicity in SK-N-SH cell lines. SK-N-SH cell lines overexpressed with CT105 exhibited remarkable apoptotic cell damage. Based on morphological observations by phase-contrast microscope and LDH activity measurements in the culture media, the CT105-induced cell death was significantly inhibited by Sesim-tang water extract. Sesim-tang was found to reduce the expression of APP and caspase-3 induced by CT105 in SK-N-SH cell lines and in rat hippocampus. Conclusions: As the result of this study, in the Sesim-tang group, apoptosis in the nervous system is inhibited, the repair against the degeneration of SK-N-SH cell lines by CT105 expression is promoted. Hence, Sesim-tang may be beneficial for the treatment of AD.

Objectives: To evaluate the pulmonary toxicity of Korean Chrysotile(KC), the lung function and the number of fibers in the bronchoalveolar lavage fluid of Sprague-Dawley rats instilled with KC were estimated. Materials: Rats were administered 1 mg KC by a single intratracheal instillation. At each time point(5 days, 5 weeks, 10 weeks), the lung function of the rats was analyzed by pressure transducer and the amount of asbestos in the bronchoalveolar lavage fluid of the rats was calculated by transmission electron microscope equipped with energy dispersive X-ray spectrometer. Results: The lung function of the rats at 5 days after instillation of KC was confirmed to be degraded. However, after 5 weeks the test groups showed a tendency to recover lung function. Still, after 10 weeks the lung function of the test groups had not recovered completely. The number of fibers in the bronchoalveolar lavage fluid of the rats instilled with KC rapidly decreased. At 5 weeks the number of fibers had reduced to approximately 1/2 of that found at 5 days. Over time, at 10 weeks it had rapidly decreased to 1/100 that found at 5 days. Conclusions: Korean chrysotile fibers rapidly decreased in the lungs of rats, but the lung function of rats instilled KC does had not completely recovered by 10 weeks.

Background : Death by cancer, malignant tumor, is on the increase around the world. In South Korea, cancer is the number one cause of death, and, in South Korea, stomach cancer is the most common form of cancer. This may be due to genetic and enviornmental factors. Because stomach cancer is so prevalent here, this study was undertaken. Objectives: This study was conducted to investigate the anti-cancer effects of Duchesnea indica(Andr.) Focke. in human stomach cancer cells(KATOIII). Materials & Methods: For human stomach cancer cells KATO III cells were obtained from Korea Cell Line Bank. The water decoction of Duchesnea indica(Andr.) Focke was added to cultures. First, morphological changes were examined under an inverted microscope. The destruction of stomach cancer cells was measured through Trypan blue exclusion testing, and suppression of viability of stomach cancer cells was measured via MTT assay. Anti-cancer mechanisms were assessed by analyzing the cell cycle. Results & Conclusions : In morphologic change, stomach cancer cells showed the withdrawn and floating appearance that is typical in cellular impairment. In each test group more stomach cancer cells were killed than in the control group to a statistically significant degree. Each test group showed more suppression of viability of stomach cancer cells than that of the control group to a statistically significant degree. Analysis of the cell cycle showed that Duchesnea indica(Andr.) Focke inhibited division of stomach cancer cells. This experiment yielded empirical evidence for Duchesnea indica(Andr.) Focke as a statistically significant anticarcinogen, specifically against stomach cancer.

Objectives: The aim is to identify any anti-tumor effects of Duchesnea indica(Andr.) Focke on colon cancer cells. Materials & Methods: Colo201 human adenocarcinoma cells were obtained from American Type Culture Collection. The boiled extract of Duchesnea indica(Andr.) Focke was added (10 and 20 microliters) to cultures and observed at 0, 6, and 12 hours, and at 12-hour intervals thereafter. Morphological changes in colon cancer cells were observed through an inverted microscope, Destruction of colon cancer cells was measured through Trypan blue exclusion testing. Suppression of the viability of colon cancer cells were measured via MTT assay. Anti-cancer mechanisms in the cell cycle of colon cancer cells were analysed via flow cytometry. Results: After introduction of Duchesnea indica(Andr.) Focke to cultures several changes were seen. Significant atrophy of the nucleus and cytoplasm of colon cancer cells was observed, indicating cell injury. Destruction of colon cancer cells was observed in direct proportion to dosage and duration. Suppression of viability of colon cancer cells for each test group was greater than that of the control group increasingly over time(36h, 48h, 60h, 72h), which was statistical significant (p<0.05). Cell numbers of the mitosis phase of the colon cancer cell cycle reduced. Conclusions: Statistcally significant anti-tumor effects of Duchesnea indica(Andr.) Focke were observed in this in vitro experiment. Results support a role for Duchesnea indica(Andr.) Focke in treatment of colon cancer. though it will required progressive research to develop a practical treatment.

Objectives : This study was aimed to investigate the therapeutic effect of Bogijetongtanggammi-bang (BJTG) on injury of the peripheral nerve tissues. Methods : Rats were divided into 2 groups. The rats of the first group were injected with Taxol (1.25 mg/kg) to their sciatic nerves, once each. The sciatic nerves of the rats of the second group were crushed by forcept for 30 seconds. Rats were administered with BJTG (400 mg/kg) or 0.9% saline for 5 days. Changes of DRG neurons, Schwann cells, Cdc2, caspase 3. phospho-p44/42 Erk1/2, phospho-vimentin and ${\beta}1$ integrin were observed by fluorescent microscope and analysed in western blot. Results : In Taxol-treated SD rat models, BJTG up-regulated neurite outgrowth, Schwann cells, Cdc2 and phospho-Erk1/2, and down-regulated caspase 3. In pressure-injured rat models, BJTG up-regulated axons of sciatic nerve, Schwann cells, Cdc2, phospho-vimentin, ${\beta}1$ integrin, and down-regulated caspase 3. Conclusions : Taken together, BJTG was promotive of nerve regeneration on SNI as well as Taxol-induced nerve injury. BJTG had a pharmaceutical property enhancing recovery of injured peripheral nerves and could be a candidate for drug development after further research.
